i would agree with comments about sizing - deff runs big. I've got a large mellon and even with the back clasp tightened all the way down I've got some wobble. with a helmet mounted night light wobble is accentuated where i'm thinking about helmet on my head not fully on whats infront of me. solution i added some additional padding to the helmet and fits much mo betta - like no worries brah! outside of non mod fit... its a slick looking helmet, lots of vents, with great coverage. when on sale I say buy it.
